Zingiber zerumbet (L.) Roscoe ex Sm.: biotechnological advancements and perspectives.

Shampoo ginger (Zingiber zerumbet) is a multipurpose ginger that has confirmed their role as food, medicine, and for decorative purposes. The rhizome possesses zerumbone, curcuminoids, and other bioactive molecules that play crucial roles in treating several human diseases. To date, several reports are existing on the in vitro biotechnology of Z. zerumbet. The present review highlights the consolidated clarification and comprehensive explanation of in vitro biotechnological implications based on plant tissue culture for the improvement of Z. zerumbet. Studies on biotechnological involvement in shampoo ginger were primarily emphasized in the study of the last 3 decades, for instance, in vitro regeneration, micro-rhizome production, callus culture, somatic embryogenesis, ex vitro establishment, and molecular assessment of in vitro-raised clones. Moreover, this review provides insights into different in vitro culture systems and endophytes involvement in the production of secondary metabolites. This review will assist for advanced research areas related to in vitro manipulation of shampoo ginger, especially for the commercial cultivation of secondary metabolites rich clones of Z. zerumbet. Moreover, it will provide an insight into crop upgrading and breeding programs of this underutilized, aromatic, and medicinal plant for amended yield and quality. KEY POINTS: • Z. zerumbet is an aromatic spice and an ornamental • This review comprehensively assesses Z. zerumbet tissue culture • Key shortcomings and future directions of Z. zerumbet biotechnology.
